Returns the index of the VoF corresponding to coarsening the input VoF by the input ratio. It is an error if the ratio is greater than the maximum coarsening ratio or if the vof does not exist at the input data index.

Returns the indices of the VoFs corresponding to refining the input VoF by the input ratio. It is an error if the ratio is greater than the maximum refinement ratio or if the vof does not exist at the input data index.

Returns the indices of the Faces corresponding to refining the input Face by the input ratio. It is an error if the ratio is greater than the maximum refinement ratio or if the face does not exist at the input data index.
